ful Improvements in Type-Writers, of which the iollowing is a specification.A

The invention relates to an improvement intypewriters and particularly to an attachment arranged for ready connection to or. disconnection from the type-A l writer and adapted for'inovably supporting one or more 'rolls for service as a paper supply to the typewriter 'ofthe base frame of the attachment, Fig. 4 is an enplaten. A 1

VThe main object of the present invention resides in the production of a typewriter attachment carrying one or more rolls of papers and an interposed roll of carbonl which are designed in the use of` the attachment to be properly fed to the typewriter platen, the construction providing for so mounting the attachment as to insure its travel in exact accordance with the travel. of the carriage of the typewriter, whereby the alinement of the paper is maintained accurate and the inconvenience incident to the supplying of the paper to the platen'in the ordinaryway is entirely avoided. l

The invention willbe. described in the following -specification, reference being had particularly to the accompanying drawings, in which:k

lFigure-l is a sideelevation illustrating the applica.-

Blocks are'connected A. by .a .transverse'frame 3 including spacedrs'idebars'@ Whichexterid parallel relation one block to the other and are conneted adjacent' eaizhend cross bars 5. Att-he ends of the bars 4, and atthe ends of the l cross bars 5, at each end of thetransverse frame, are provided depending pins 6, designed to `enter openings 7 ormed'in'the upper surface of each Vbasey block. Inwardly from -thel point of'attachment to the base blocks the side bars 4 of the transverse frame are projected 'movableconnection at 10 with the bars 4, and yextending forwardly at a right angle'to said bars. Each of the bars 9 is formed with sockets 11 and 12, the former being arranged at the end of the bar and the latter about midway its length. Sockets are thus provided for the reception of the feet -13 of the typewriter 14, whereby the main frame of the attachment is held in proper op'era-Y tive relation to the typewriter when in use.

The base plates 1 are centrally formed with sockets l5 designed respectively to receive end standards 16 and 17 for the support ofthe paper rolls, as hereinafter described. The standard 1'6 is formed on its relatively inner face with a series of longitudinally disposed supporting shoulders 18, preferably formed by suitably stamping or indenting the material of the standard, as

clearly shown in Figs. 7 and 8. The standard 17 is lformedV in its relatively inner wall with a series of perforations 19, respectively arranged in transverse aline- -ment with the shoulders 18 when the standards are in operative position. The standards 16 and 17 are preferablyof hollow construction, to afford lightness, and the standard 16 is made in two sections by a transverse vdivision below the shoulders 18, the sections being Connected by a hinge'connection 20 on the relatively outer wall of the standardf'and maintained in alined or vertical position by a gravity latch 21 slidably mounted on the "relatively inner wall of the upper section andengaging akeeper 22 on the lower section, as clearly shown in Figs. 2 and 9. The upper section of the standard 16 is thus adapted to be moved in a direction away from the standard 17, to permit removal or insertion ofthe roll carriers, as will presently appear.

nection with therespective standards, one end seating loosely on one of the shoulders 18, and the other end being preferably squared at 24 for insertion' in one of the squared openingslQ in the standard 17.

25 represents whatwe term a roll carrier, comprising a sleeve-like body ofa size to encircle the shaft 23 and of, a length somewhat in' excess of the desired width of I.

' the paper to be used. The cairier is interiorly provided with bearing blocks l26 recessed for the receptionpf v balls, the relatively upper portion of the shaft 23 being also recessed at 28 for the reception of the balls 27. The carrier is thus supported on the shaft for independent longitudinal movement, the mounting `of the shaft preventing revolution oi tho carrier,

the ring4 and carrier.

' typewriter papers,

Y aration, after printing, into sheets o 37 and squared, as at 41,

vtion' oi the platenserving tive sheets of paper trom the rolls, and the 'longitudinali lower-roll ot typewriter paper as will bc evident. The respective ends ol the carrier nrc toi-mcd at diametrically*opposed points with integral eyes 29, preterably arranged at the extremity of the vertical diameter oi the carrier, as clearly shown in Fig. 4.

lari-ier arms 30 are arranged at each end oi the carrier, being formed at the carrier end with ring members 3l of materially greater diameter than that ol' the carrier. The ring members are designed lobe arranged in alinement with the respective ends oi the carrier, and are formed with diametrically opposed eycs 32 and 33 arranged in pairs, as shown, one eye ol' each pair being alined with one oi the eyes 2S) at cach ond of the carrier. The carrier and ring 3l are secured togetherby a Ill-shaped key 34, the arms Il?) ot' which are designed to be passed through the respectively alined eyes on The ring of each arm 30' is thus supported concentric with the carrier, and removably secured theretothrough the medium of the key. The arm 30 projects forwardly from each respective ring,- being provided at its forward or tree end with a clamping member 3G to provide tor removable attachment oi' the arms to an appropriate part ot the typewriter carriage l or platen, whereby said arms, and thereby the carrier may be moved simultaneously and coincidently with the carriage or platen.

Hanger arms 37 depend from the respective rings 3l, being of* Va length to receive and support' roll shafts 39 and 40, for a purpose which will presently appear. Y The shaft 39 is preferably projected beyond one of the arms or the reception o an operating had,'not shown, wherebysaid shaft may be manually operated 'as desired, I

In use a roll of paperVlZ, oi the/desired width for the typewriter, is supported upon the carrier 25, a roll ot carbon paper 43 being supported upon the shait 39,and a second roll o typewriter paper 44 supported upon the y shaft 40. The standards are arranged to support the respective shafts and the holding plates 9 disposed to receive the typewriter.` The arms 30 are connected at appropriate points with the platen, ,and the ends oi the with the carbonstrip interposed are passedbeneath the platen in the usual malin/er. The typewriter is operated in the ordinary way,- the revoluto properly ieed the respecniovement oi vthe platenorl carriage feeding the carrier and supported rolls oi paper vand carbon longitudinallyl o the attachment frame coincidently and identically with the carriage movement. v The paper is thus maintained at all times in proper alinement with the. printing plane, andthe operator is saved time incident to the removal of printed sheets and the insertion of others.. If desired the rolls of typewriter paper may be perorated 'or scored transversely to provide for, the ready sepy the desired length.l I a carbon duplicate is not desired either the upper or I may be .used without regard to the other rolls, thereby providing a single copy of the matter printed.

The lframe of thel attachment is readily collapsible for close storage when not desired for use, and the standard 16 may be broken at its hinge joint toprovide for the -suring an absolute ,a tie 4frame uniting the release oi the shaft 23 when the insertion of additional paper is necessary,

. 6 5 The device as a whole provides a simple and effective `means ier maintaining a continuous supply oi paper `to a typewriting machine, the particular construction inalinement oi the paper with the' printing plane, and the convenient removal or ins'er- '70 tion o additional rolls oi the 'paper when desired.v As

the carbon strip is capable ot' continued reuse, provision is made, as previously described tor the manual winding oi said roll after use oithe carbon, whereby the carbon strip is adapted for reuse as long as a clear imy7,5 pression is obtained.

While preferring the described details oi construc-y tion shown and described it is obvius that various changes may be resorted to without departing from our invention, and we wish it distinctly understood that we contemplate, as within the spirit ol our invention, all such changes and variations in construction and arrangement as may all within the scope oi the appended claims.
